Sentinel Distance · Uncommitted

Natalia was a competitive softball player who did not find her love for running until later in her career, after battling back from several early injuries. She is putting together one of the most impressive female distance careers in Seton Catholic history. She is currently uncommitted to run at the next level but is interested in doing so.
